Embodiment
Below with reference to the drawings and specific embodiments the present invention is described in further details.
As Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, rotary type fluid-distributing valve of the present invention, it comprises valve body 4, rotary spool 12, drive motor 10, closed end cap 2 and open end cap 5, the two ends that closed end cap 2 and open end cap 5 are connected to valve body 4 form enclosed cavity 18, rotary spool 12 1 ends that are installed in the enclosed cavity 18 link to each other with drive motor 10, closed end cap 2 and rotary spool 12 in the enclosed cavity 18, form high-voltage oil cavity between the valve body 4, open end cap 5 and rotary spool 12, form the low pressure oil pocket between the valve body 4, be not communicated with between high-voltage oil cavity and the low pressure oil pocket; The outer circumferential side of valve body 4 offers several valve body oilholes 14 that is used for connecting the power unit oil circuit, and the outer circumferential side of rotary spool 12 offers several spool oilholes 15, and valve body oilhole 14 is communicated with enclosed cavity 18 by spool oilhole 15.
Valve body 4, rotary spool 12 closed end caps 2 and open end cap 5 all adopt revolving parts, referring to Fig. 2 and shown in Figure 3, valve body 4 is as whole device main body part, and closed end cap 2 and open end cap 5 are fastenedly connected with valve body 4 by first screw 3 and second screw 6 respectively.Rotary spool 12 is installed in closed end cap 2 and the open end cap 5 by first deep groove ball bearing 1 and second deep groove ball bearing 7, and can be around self geometrical axis rotation.Be rotated motive sealing by o RunddichtringO 13 between the drive shaft section of rotary spool 12 and the open end cap 5.Drive motor 10 is installed on the open end cap 5 by electric machine support 9, and is connected with the axle of rotary spool 12 with the output shaft of flat key 8 with drive motor 10 by coupling 11.Offer n valve body oilhole 14 that is used for connecting the power unit oil circuit on the cylindrical side of valve body 4 outer circumferential sides, wherein n is an even number, and two the valve body oilholes 14 that are positioned on valve body 4 diametric(al)s constitute one group.Rotary spool 12 is installed in the inside of valve body 4, and with valve body 4 between cooperate by the cylndrical surface.When rotary spool 12 was in different rotary positions, the valve body oilhole 14 of diverse location will be respectively and high-voltage oil cavity or the conducting of low pressure oil pocket on valve body 4 cylindrical sides.
Referring to illustrated in figures 1 and 2, the end face of the end face of closed end cap 2 and valve body 4 is fitted, and is fastenedly connected by first screw 3.Closed end cap 2 is provided with an oil inlet hole, can link to each other with gear pump, the contour pressure oil feeder of accumulator, the hydraulic oil that has certain pressure in order to input, in addition there is not the passage that other links to each other with the external world, therefore even when its high-voltage oil cavity inside with valve body 4, rotary spool 12 parts composition contains high pressure oil, also can not cause leakage to external world.The opposite side end face of the end face of open end cap 5 and valve body 4 is fitted, and is fastenedly connected by second screw 6.There is an oil outlet in the outside of open end cap 5, can be connected with fuel tank.In addition, the turning axle place of open end cap 5 has a circular port, stretches out in order to the live axle with rotary spool 12.Because the oil pocket that open end cap 5, rotary spool 12 and valve body 4 are formed is the low pressure oil pocket, promptly its inner oil pressure is very low, so 13 sealings of o RunddichtringO can be directly adopted in the sealing between open end cap 5 and the rotary spool 12 without the lip-type packing oil sealing.
Referring to Fig. 2 and shown in Figure 4, have n spool oilhole 15 on the cylindrical side of rotary spool 12 equably, wherein n is an even number, per two spool oilholes 15 that are positioned on rotary spool 12 diametric(al)s constitute one group.When rotating to correct position, these spool oilholes 15 can communicate with the valve body oilhole 14 on valve body 4 cylindrical sides.In order to guarantee that each oilhole has more ON time, offer shallow slot 16 between the adjacent valve core oil hole 15 on the rotary spool 12.On the both sides end face of rotary spool 12 main bodys, be processed with one section curve bath 17 respectively, this curve bath 17 is communicated with the n/2 on this part cylindrical side adjacent oilhole, thereby accelerates the turnover speed oil.
Working principle is introduced: a certain moment, the high-pressure and hydraulic oil that oilhole from closed end cap 2 enters flows into high-voltage oil cavity, and be full of the curve bath 17 on right side on the rotary spool 12, further flow into n/2 the valve body oilhole 14 that communicates with curve bath 17, this moment, this n/2 oilhole 14 communicated with adjacent n/2 spool oilhole 15 on the valve body 4, thereby with the oily derivation of high-pressure and hydraulic rotary type fluid-distributing valve; Remaining n/2 spool oilhole 15 communicates with n/2 valve body oilhole 14 of remainder on the rotary spool 12 simultaneously on the valve body 4, extraneous low-pressure hydraulic oil flows in the curve bath 17 in rotary spool 12 left sides by spool oilhole 15 and valve body oilhole 14, and be full of the low pressure oil pocket, flow out rotary distributing valve by the oilhole on the open end cap 5, form a complete oil circuit; When rotary spool 12 rotates under the driving of drive motor 10, curve bath 17 in right side and left side is in diverse location respectively on it, but still communicate with high-voltage oil cavity and low pressure oil pocket respectively separately, thereby make adjacent n/2 spool oilhole 15 of the diverse location on the valve body 4 communicate with high-voltage oil cavity/low pressure oil pocket respectively; Shallow slot 16 on the rotary spool 12 communicates adjacent n/2 the valve body oilhole 14 identical with curve bath 17, thereby makes that the time of each spool oilhole 15 conducting increases to rotating the shallow slot required time of 16 length on the valve body 4.
